Overdrive: Sparking Wires?

I just finished my overdrive flourescent fixture. Its 2 20watt bulbs overdrived 4x. When I first plugged it in one of the wires in the wire nut began to spark. I tightened the nut and it seemed to fix the problem. Now I'm paranoid about leaving it unattended. Can anyone offer some insight as to why this occured? I'd hate to catch my apartment on fire.

Sparking at connections means the wires were just barely touching, and the current makes them separate slightly, which makes the current go thru the air, which is a spark. If you get all of the wires in the connection twisted together before you install the wirenut you should never have a problem. (An electrician taught me that several years ago. Before that I just lined all of the wires up straight and relied upon the wirenut to twist them together.)

Ok. Are you talking about grounding the white wire? I've got the black wires connected to the switch thats connected to the AC line. The white is connected to the other AC line. Hope this makes sense as I'm not that educated in eletrical circuits.

I don't have a green wire. Also, the power cord only has 2 prongs.
